HOSIERY MANUFACTURE Prior Application: Priority, Great Britain, 9thFebruary, 1974, Application No. 6003/74.

The present invention concerns improvements relating to hosierymanufacture. More particularly, the invention relates to an improvedeverting or reversing apparatus.

During manufacture of stockings, tights and the like, some operationsare customarily effected with the hose inside out. A typical example isthe toe-closing operation. At a later stage in the manufacture, the hoseare conveyed pneumatically to a collection station. It is desirable thatthe hose are delivered the right side out,

'and a turning or reversing apparatus is therefore desirable.

According to one aspect of the present invention, there is providedeverting apparatus for hose-making plant, comprising a suction tube,roller means for drawing hose welt-first onto the tube until a toeportion of the hose engages the tube, the roller means thereupon beingoperable to exert and maintain a presettable tension on the hose, andmeans for applying suction to the tube and for relieving the tensionexerted on the hose, thereby allowing the hose to be sucked toe-firstinto the tube and accordingly causing the hose to be turned or everted.

Advantageously, the everting apparatus includes flattening means forflattening a toe seam, the flattening means being operable while thetension is maintained on the hose. The flattening means can take theform of a punch seam straightener. This may comprise a reciprocaltubular member telescoped within the suction tube. In use, the tubularmember is forcibly advanced so as to protrude from the toe end of thesuction tube while the hose-drawing means tension is maintained on thehose.

It is preferred that roller drive means is provided including apresettable slipping clutch which governs the tension exerted by theroller means. The roller means can comprise at least one and desirablytwo gripper rollers.

In a preferred embodiment, the hose drawing means comprises, incombination, reciprocable and releasable clamp means movable lengthwiseof the tube to draw the hose partly onto the tube, and a pair of rollersfor drawing the remainder onto the tube and for tensioning the hose.Conveniently the rollers are mounted for movement between an idleposition and an operative hose drawing position out of, and inengagement with the said tube and hose, respectively. Tension is thenrelieved by moving the rollers to the idle position. Alter- ;natively,the or each roller could be fixedly mounted in continual lightengagement with the tube, in which case the said roll should be capableof free-wheeling when suction is applied.

In the preferred embodiment, ,the pair of rollers are mountedindividually on rocker arms, and the latter are rocked, via cammingmeans actuated in timed response to movements of the clamp means, toengage and disengage the rolls with the suction tube.

Apparatus embodying the invention desirably is controlled by cammingmeans and rams for simplicity and reliability.

The invention will now be described by way of example with reference tothe accompanying drawings, in which:

FIG. 1 is a general perspective view of a toe closing machine,

FIG. 2 is a side elevational view of a hose reverser assembly embodyingthis invention,

FIG. 3 is a top plan view of the assembly shown in FIG. 2,

FIG. 4 is a sectional view of the reverser assembly taken along the lineIV-IV of FIG. 2, and

FIG. 5 is another sectional view taken along the line VV of FIG. 2. i

The machine 10 shown generally in FIG. 1 is a semiautomatic toe-closingmachine for use in hosiery manufacture. The machine may be used whenmaking fullhose (stockings and tights) and half hose (socks). Control ofthe machine is generally via cams and switchable pneumatic operators.

The machine 10 includes a seaming device 12 for providing a toe-closingseam. The device 12 could be an adhesive applicator for adhesiveseaming, but in this case is a sewing machine 13 fed with thread from asupply bobbin 14. A clamp assembly, not visible behind a machine panel15, is located adjacent the sewing machine 13 for holding hose securelyduring the seaming operation. A carrier leg assembly 16 is provided toreceive an unseamed hose and topresent it to the clamp assembly. To oneside of the carrier leg assembly 16 there is a reverser assembly 18. Thepurpose of the reverser 18 is to turn a seamed hose inside out, suchthat the seam is positioned within the toe of the finished orpart-finished hose.

The machine 10 is used as follows. An operator is supplied with hoseblanks to be toeseamed, which may arrive in a twisted state. A blank ispresented toe end first to a suction tube associated with the carrierassembly 16. The suction tube sucks in the blank up to its welt, whichis firmly held by the operator. Then the operator threads the welt ontothe carrier leg 16 and throws an actuating lever 19. This causes aroller 20 to rotate and draw the hose blank onto the carrier leg 16 in astraightened condition. The operator now aligns the blank with anidentification mark on the carrier leg 16 and thereafter depresses afoot pedal 21. The carrier leg 16 is then operated to advance the hoseblank towards the clamp so as to present the toe end of the blank to theclamp. The blank is then clamped thereby and the carrier leg isretracted. Next the toe end is sewn and the blank is thereaftertransferred to the reverser assembly 18. Conveniently, transfermechanism which transports the now-sewn hose to the reverser assembly 18is arranged to initiate operation of the latter. The reverser assembly18 is adapted to discharge the hose neatlyto a collecting station readyfor subsequent operations to be performed thereon. Such operations caninclude, for example, the stitching together of companion legs to formtights.

Further details of the general construction and oper ation of themachine illustrated in FIG. 1 can be found in the Complete Specificationfiled on our co-pending applications numbered 26481/72 and 529ll/72.

The improved reverser assembly embodying the present invention will nowbe described, and reference will be made to the remaining Figures of thedrawings.

The reverser assembly includes a suction tube shown generally at 30 uponwhich a hose to be reversed is drawn initially. The suction tube 30 isopen at its hosereceiving end 31 and has a connection 31a at its otherend to a suction pump (not shown). When suction is applied to the tube30, a hose mounted thereon can be sucked through its open end 31,thereby drawing the hose off the tube 30. In the process, the hose isreversed or turned inside out.

Associated with the suction tube is a clamping or holding means 32 and awind-on or tensioning means 33. The clamping means 32 is mounted forreciprocal movement lengthwise of the tube 30 on a carriage 34 whichruns on a pair of rods 36. The rods are fixedly held in a mounting frame37 of the reverser assembly, the rods being disposed above the tube 30and extending parallel thereto. The clamping means 32 includes anarcuate shoe 38 at one end of a leg 39 which is pivoted at 40 to thecarriage 34. It will be seen that the clamp shoe 38 can be moved towardsand away from the tube 30 if the clamp leg 39 is rocked about its pivot40.

Drive means for reciprocating the carriage 34 and hence the clampingmeans 32 lengthwise relative to the tube 30 comprises a pneumatic ram R1having a piston rod 41 connected to the carriage 34.

Clamping and releasing movements of the clamping means 32 are effectedby camming means Cl, F1. An elongated, slotted cam plate 42 is mountedalongside the carriage rods 36 for reciprocal movement parallel thereto.Movements of the cam plate 42 are effected by operation ofadouble-acting ram R3. The cam plate 42 has an elongated slot 43, themajor portion of which forms a straight dwell, and rise portions 44, 45adjacent the slot ends. The follower Fl rides in the cam slot 43 and isable to traverse substantially the whole length thereof. The follower ismounted on a free end of the clamp leg 39 located at the opposite sideof the pivot 40 from the clamp shoe 38. It will be appreciated thatmovement of the cam plate 42 to the right will, as seen in FIG. 2, causethe follower end of leg 39 to rise. Accordingly, this movement will beaccompanied by clamping movement of the shoe 38 towards the tube 30.

The wind-on means 33 comprise a pair of rollers 50, 51 having associateddrive means 52. The rollers 50, 51 are mounted on a pair of arms 53, 54which are pivotally mounted to allow their rollers to be swung towardsand away from the tube 30. When the upper roller and its arm 53 arelocated away from the tube 30, there is a space allowing the clamp arm39 and clamp shoe 38 to move past the roller 50.

The drive means 52 here comprises an electric motor 55 which drives afirst pulley 56 through a slipping clutch 57. A main drive belt 58 istrained around pulley 56 and a second pulley 59, so as to drive a gear60 and a third pulley 61. A second drive belt 63 is trained around thepulley 61 and a fourth pulley 65 is fast with the upper roller 50. Thelower roller 51 is driven in a similar manner as the upper roller, itsdrive being obtained through a gear 66 in mesh with gear 60. The rollers50, 51 rotate in opposite senses so as to effect a wind-on action.

It is preferred that some or all of the pulleys and drive belts aretoothed. Smooth pulleys/belts could be used, and if appropriate tensionwere employed, it might be feasible to dispense with the slipping clutch57.

Further camming means 70 are provided to move the rollers 50, 51 andtheir arms 53, 54 towards and away from the tube 30. Additionally, thecamming means 70 are arranged to move the arms in timed relation to thereciprocal movement of the clamping means 32.

The camming means 70 comprise a cam lever C2 which is journalled to aframe memberat 72 for pivoting movement. The cam lever C2 includes apair of curved cam slots 73, 74, receiving followers F3, F4 which aremounted on the roller arms53, 54 respectively. The cam slots are shapedto define relatively long dwells, when the arms 53, 54 and their rollersare spaced away from the tube 30, and relatively abrupt cam drops foreffecting sudden movement of the rollers towards the tube 30.

A lost-motion connection is provided between the cam lever C2 and themovable carriage 34. The lostmotion connection serves to establish thetimed operation of the rollers 50, 51 with respect to the clamping means32. The connection comprises an elongated slot 75 in the cam lever C2and a cam follower F2. The latter is mounted on a leg 76 on the carriage34. It will be appreciated that movement of carriage 34 along the rods36 to the left, as seen in FIG. 2, will cause the cam lever C2 to swinganti-clockwise in the journal 72. As this happens, the cam slots 73, 74move relative to the followers F3, F4, and ultimately cause the rollersto shift inwardly towards the tube 30. The arms 53, 54 are themselvesjournalled about the rotation axes of the associated drive gears andpulleys, e.g. 60, 61, 66. Thus, as they rock, the tensions in theirdrive belts remain substantially unchanged.

The suction tube 30 comprises an outer tube 79 and a slideable innerpunch tube 80 to the interior of which the suction is actually applied.Tube 80 is intended to serve as a seam-flattener. The suction tube 79itself terminates at 81 clear of the suction inlet 82, thereby exposinga portion of the punch tube 80. The exposed portion carries a yoke 83which is connected to an actuator in the form of a double actingpneumatic ram R2. Contraction of the ram here causes the punch tube 80to move to the right so as to protrude from the outer tube 79 at end 31.

With the exception of the electric motor 55, drive elements of thereverser assembly comprise pneumatic actuators or rams. These arecontrolled by a set of valves including V1 to V4 in the illustratedembodiment. If the carriage 34 is moving to the right, a camming ramp 85thereon engages a link 86 coupled to the valve V1 as the carriage nearsthe end of its forward movement to the right. As illustrated in FIG. 2,the

valve V1 has been actuated so as to retract ram R3 and withdraw camplate 42 to the left, thereby causing release of the clamping means 32from the suction tube Valve V3 is located with an actuator linkthereofdisposed towards the left hand end of the path of travel of the carriage34. The link 88 is displaceable by a second camming ramp 89 on themoving carriage 34. When displaced, the link 88 actuates the valve .V3to allow pressure presently applied to ram R1 to operate a pressureswitch (not shown) controlling the motor 55 to switch the latter on.Actuation of V3 may also set in train the starting of a timer. The timercreates a delay allowing a full hose to be wound fully onto the tube 30before subsequent operations of the machine occur. The timer is arrangedto actuate ram R2 which drives the punch tube 80 to the right. Finally,valve V3 actuates ram R3 to withdraw the cam C1 to the left, to lowerthe clamp shoe 38 onto .the tube 30, the clamp shoe 38 having previouslybeen raised when follower F1 rode along rise portion 45.

Valve V4 is actuated by a push-rod 90 by the yoke 83 when the punch tube80 has been fully extended, and serves to reverse the operation of ramR1 to return the clamping means 32 to the right. The changed pressureconditions in R1 concomitant with reversal of the operation thereof act,via the afore-mentioned pressure switch, to stop the motor 55. V4 alsooperates to actuate ram R2 for withdrawing the punchtube 80.

Then V2 is operated by the camming ramp 85 when the carriage 34 beginsmoving to the right. When operated, V2 admits air to the ram R3 wherebycam C1 is shifted to the right to maintain the clamp shoe against thetube 30. The camming ramp 85 then operates valve V1 to shift cam 42 tothe left via ram R3 to raise the clamp shoe 38 away from the tube 30 forcommencement of the next cycle of operation. 2

Whilst pneumatic actuators are presently preferred, hydraulic actuatorscould be substituted Furthermore, it is feasible for electric solenoidactuators to be used.

The operation of the reverser assembly will now be described. A transfermechanism of an associated machine or a human operator positions thehose to be reversed welt-first onto the end 31 of the suction tubeassembly 30. The reverser is then started, manually or automatically, toactuate the ram R3 to advance cam C1 to the right. In response the,follower F1 shifts the clamping means 32. from the illustrated positionto a clamping position, therebyholding the welt of the hose on the endof tube 30. I

Air is then applied to ram R1 to draw the carriage 34, the clampingmeans 32 and the hose to the left onto the tube 30. The arrangement issuch that the moving clamping means 32 pulls the weltto the left beyondthe rollers 50, 51. The movement permitted of the welt is limited by astop 91. When the clamping means 32 has passed the rollers, its followerF1 enters the cam rise 45 and the clamp shoe 38 is released from thetube-30.

While the carriage 34 and clamping means 32 are tion applied to the tube30 draws the hose toe-first into the tube 30. Motion of the hose intothe tube 30' is assisted by the forwardly-moving clamping means 32.

During its forward movement, the carriage'34 trips the valve V2.Thereupon V2 actuates ram R3 and shifts the cam Cl forwardly to maintainthe clamping means 32 in a clamping position until it reaches the end ofits forward stroke. The carriage 34 then trips V1 to actuate cam C1, andthereby to raise the clamping means to the released position as in FIG.2, ready for the next cycle of operation.

After passage through the equipment described and illustrated'above,reversed hose are discharged to the I left of FIGS. 2 and 3 in astraightened condition, right sides but and with well-flattened toeseams.

' We claim:

1. Everting apparatus for hose-making plant, comprising a suction'tube,roller means for drawing hose welt-first onto said tube to dispose a toeportion of the hose in engagement with the end of said tube, said rollermeans thereupon being operable to exert and main tain apresettabletension on the hose with the toe end I thereof in engagement asaforesaid, and means for applying suction to said tube and for relievingsaid tension exerted on the hose, whereby the hose is sucked toef rstinto said tube and accordingly is caused to be everted. I

2. Everting apparatus according to claim 1, including flattening meansoperable to flatten a hose toe seam, said flattening means beingoperable while said tension is maintained on the hose.

3. Everting apparatus according to claim 2, wherein said flatteningmeans comprises a reciprocal tubular member movable telescopicallywithin said suction tube. I v i i I .4.

Theroller arms 53, 54, are moved inwardly into engagement with the tube 30by the time the clamping means is released therefrom. 1

As the carriage 34 commences its leftwardmovement, the motor is switchedon by the pressure switch actuated by pressure in the ram R1. As thecarriage 34 nears the end of its leftward movement, it trips valve V3.This valve (i) starts the aforementioned timer provided, and (ii)actuates ram R3 to shift cam C1 to a clamp-applying position whereby theshoe 38 is brought once more into engagement with the tube 30. The motor55 drives the rollers 53, 54 to pull the hose fully onto tube 30, untilits seamed toe is disposed across suction tube end 31. The tensionexerted by the rollers on the hose is governed by the setting of theslipping clutch 57 or the tension in roller drive belts if a slippingclutch is omitted.

When the ram R2 has extended the punch tube 80 fully to the right, thusstretching and flattening the hose toe seam, valve V4 is actuaged. V4operates ram R2 to retract tube 80 and reverses ram R1 to bring about areturn movement of the carriage 34 and clamping means 32 and to switchoff motor 55 via the appropriate pressure switch. During its return tothe right, the clamp shoe 38 rides along the tube 30 and as it does sothe rollers 53, 54 aremoved apart, their control cam C2 rockingclockwise in response to the moving carriage 34.
